Know More About Electric Vehicles
You must have heard a lot about electric vehicles and their advantages as well as limitations. Here you can learn more about different types of electric vehicles.
Hybrid EVs (HEVs)
Hybrids EVs have high fuel efficiency in city driving but this advantage dwindles on high speed roads where battery weight impacts on fuel consumption. These can be viewed as short-term bridging technology vehicles, being superseded by plug-in hybrid and full EVs. These could cost around a 20% more than an equivalent petrol or diesel vehicle, due to the additional cost of the battery, electric motor and associated equipments.
Plug-In Hybrid EVs (PHEVs)
Hailed as the new generation of hybrid vehicles, they are primarily used for short journeys powered by the on-board battery and achieve significant greenhouse gas emission savings. The two main barriers to their current uptake are battery technology and the availability of a widespread recharging infrastructure. Knewron has already begun research & development work on improving the access to a network of recharging posts and other relevant ancillaries.
Full Battery EVs (BEVs)
They face similar barriers to widespread adoption as plug-in hybrid EVs, with infrastructure, public perception and battery issues all magnified. Batteries are the major technological barrier to EV commercialization. The leading battery chemistry for EVs in the short to medium-term is lithium ion. It is expected that BEVs will achieve dramatic CO2 reductions as the nations decarbonizes their electricity supplies.
Extended Range EVs (EREVs)
Primarily this is also an EV but also utilizes a small IC (Internal Combustion) engine driven alternator to generate electricity. This differs from normal hybrids as the primary drive is always via the electric motor. EREVs are seen by many as the ultimate goal for EVs, due to their high efficiency and ability to be topped up with conventional fuel when required. This removes 'range anxiety' for even the longest journey. EREVs can give a range of about 60km using battery power alone, with a total range in excess of 400km.
